Polyadenylation of mRNAs preceded by specific endonuclease cleavage has been demonstrated in Ch. reinhardtii chloroplasts. The plastid gene named me for its similarity to the E. coli RNase E is involved in this process. The chloroplast me genes were discovered in the same algal genomes that contain the mpB gene. In land plants, the me genes are located in the nucleus. 

In land plants and algae, the prokaryotic fis and min genes involved in plastid division and cpDNA replication have been discovered. The products of the min genes-MinD and MinE-interact with the tubulin-like FtsZ protein, which participates in plastid division. FtsZ is encoded by a nuclear gene family. The minD and minE genes in C. vulgaris and G. theta are located in cpDNA. 

The cpDNA of aU nongreen algae encode the metaUoprotease FtsH. In land plants, this enzyme is nuclear-encoded. The FtsH proteins play an important, though not completely understood, role in chloroplast biogenesis.
